Ratio of Debt-to-Income

The ratio of debt to income is a tool lenders use to calculate how much money is available for your monthly home loan payment after all your other recurring debts are met.

How to figure the qualifying ratio

Usually, underwriting for conventional mortgage loans requires a qualifying ratio of 28/36. FHA loans are less strict, requiring a 29/41 ratio.

The first number in a qualifying ratio is the maximum amount (as a percentage) of your gross monthly income that can be applied to housing costs (this includes principal and interest, private mortgage insurance, hazard insurance, taxes, and HOA dues).

The second number is what percent of your gross income every month that can be applied to housing expenses and recurring debt. Recurring debt includes payments on credit cards, vehicle payments, child support, etcetera.

Some example data:

28/36 (Conventional)

  • Gross monthly income of $4,500 x .28 = $1,260 can be applied to housing
  • Gross monthly income of $4,500 x .36 = $1,620 can be applied to recurring debt plus housing expenses

With a 29/41 (FHA) qualifying ratio

  • Gross monthly income of $4,500 x .29 = $1,305 can be applied to housing
  • Gross monthly income of $4,500 x .41 = $1,845 can be applied to recurring debt plus housing expenses
